Can anybody tell me which group is more reliable ?

[武斌]

Hi,everyone!
      I'm a fresh man in Hadoop, and when I install the Hadoop I have met a
lot problem.
      Now my question is which group below is more reliable ?
          (1)hadoop 1.14.1 with jdk 1.5
          (2)hadoop 1.15    with jdk 1.6
          (3)some else?
      Which one is the best composition? I  expect that my FS is more stable
and reasonable.
      THX!
